OnJava.com have a simple article on installing and configuring JBoss – it covers basic installation and configuration. Nothing earth shattering in detail, but a basic introdution if you are not familiar with the server.
Is Java the new Cobol?
Tim Bray, co-inventor of XML, recently listed everything in the industry that he considers boring or not boring in his blog.
His point being that good news is often boring; it’s not exciting as bad news, and good news is often about things that are safe and predictable.
Java, in his opinion, has become boring. It’s reached a stage in it’s development where it is now accepted in many different application development areas (financial, telecoms, healthcare, etc) as a good, stable, reliable platform on which to build applications – Java has become the new Cobol.
This is an interesting perspective, but one that is great for everyone currently working with Java – it is truly mainstream and acceptable, and is no longer considered a risk. Companies are building multimillion dollar systems using Java, and it is accepted as a viable platform for building solutions.
All good things usually come to an end however. I don’t see that end as being .NET – Java has too much industry momentum to be overtaken or replaced by .NET. I see the main changes coming as a shift in development technology, possibly with AOP. Just as assembly was superceeded by high level languages, I think OO languages such as Java are going to not be replaced, but eveolve into more AOP like development languages. Java of course already has interest in these areas with Spring AOP, JBoss AOP, and AspectJ.
Versant slam Hibernate – Gavin King responds
Gavin King has recently posted to the Hibernate blog wesite with a set of responses to issues raised by Versant comparing their ORM product to the (apparently inferior) features Hibernate.
Gavin replies to each of the points raised by Versant, correcting their understanding and illustrating how Hibernate does indeed provide features indentified by Versant as missing.
I haven’t seen the original email from Versant, but it seems like an attempt to spread some Fear, Uncertainty and Doubt in the ORM world. I wonder how much Versant’s business is hurting as a recent of the success of Hibernate?
Article on using annotation for data constraints
There’s an interesting article on the Sun Java site this week about how to use 1.5 Annotations to enforce data constraints on Java Beans. This is a very neat approach to enforcing rules like max lengths on bean properties.
